    Never buy from SkyRC

    After 2 months of battling with skyrc, I have admitted defeat. Two of skyrc's chargers failed within 2 weeks. One was just a button, but the other misread my battery voltage and caused them to over charge and puff up. They said they would cover them, but they never did. After the worst customer...

    That's what I thought... Thanks for the second opinion.

    Battery puffed due to faulty charger please help!

    Ok, so my charger ended up showing a lower voltage than was really there, causing it to over charge the battery. I used a SkyRC RS16. My batteries puffed (see picture) and are WAY over voltage (17.60 and 17.80). I currently have them outside in a hard metal trash can. I'm pretty sure I am going...

    Help: Turnigy vs Multistar?

    Alright, thanks so much! I will Just run with the SkyRC since it's plug & play, and allows me to have a read out on my computer.

    Help: Turnigy vs Multistar?

    Ok, so what I am getting from this is don't build a charger yet. Go for something that is pre-made until I have done more research on building these things (Probably a good idea xD). Any pre-made RC chargers/dischargers that you would recommend? I was thinking of the SKYRC RS16 before this.

    How would I set up these chargers? I don't know anything about it so I don't really know how to judge for myself. Please link me something that will teach me what I need to know. This does look pretty awesome though, especially for the price

    Awesome! I plan on using this bike quite a bit to get to and from campus so I will be collecting a ton of data on it's voltage and capacity over time. Hoping they will last me at least a year!

    How do you wire the HLG to charge? I don't know anything about them since I wasn't intending to build my own charger, but now that you said it charges your 20Ah packs in around an hour I am super interested! I was looking at this: https://endless-sphere.com/forums/viewtopic.php?f=3&t=62174 but I...

    Help: Turnigy vs Multistar?

    Could you link me where to get the meanwell and bulk charger? I'm hoping to spend around 120$ on the charging system. Is that reasonable?

    Help: Turnigy vs Multistar?

    Forget the BMS, it's not needed and is just another thing to go bad. Your controller should have a LVC @ 41 Volts, perfect for 12S and that, plus a Voltmeter, is all you need for the dis-charging cycle. To charge, you should use a bulk charger and two Battery Medics for ck'ing and balancing the...

    How does it compare to the Turnigy one though? Are they equally stable/long lasting?

    Help: Turnigy vs Multistar?

    I plan on building my first RC LiPO battery pack this year for my ebike and was planning on getting this Turnigy battery pack (http://www.hobbyking.com/hobbyking/store/__18631__Turnigy_5000mAh_4S1P_14_8v_20C_Hardcase_Pack_US_Warehouse_.html). I saw this Multistar pack on sale though...

    Need help with picking a battery for Leafmotor

    So, if I got either of these two: http://tinyurl.com/jrhfmr4 or http://tinyurl.com/create.php : would that give me roughly what I would want? If so, which one would you say is better for my application? 45 mph and 20 miles were just "If it's possible" numbers. I'm about 175 if that helps at all.

    Need help with picking a battery for Leafmotor

    I am pretty new to the ebike scene, but I have decided on the new Leafmotor 1500W because I do understand that motor (http://tinyurl.com/hu27q5c) but I am not very knowledgeable about the controller that comes with it and what V/A would be best for longevity and stability at the speed I want...
